Subject: [PATCH 2/4] clk: Use struct clk_hw instead of struct clk_core for debugfs

The clk debugfs code uses struct clk_core because it is part of the core
framework file where the struct isn't opaque. Introduce helpers that use
struct clk_hw and use them in the clk debugfs code so that a later patch
can split out the clk debugfs code to a loadable kernel module while
keeping struct clk_core opaque.
